71, 0.71, and 0.77, and the cutoff values were 9.4, 9.4, and 11 kPa, respectively. Multiple regression analysis showed that LSM was positively correlated with degree of fibrosis and NAFLD activity score. UAP was positively correlated with liver steatosis. The diagnostic performance of UAP for steatosis was significantly superior to that of the hepatic steatosis index.
FibroTouch has a low failure rate with moderate to high diagnostic performance for discriminating the steatosis degree and fibrosis stage and is suitable for clinical evaluation and monitoring of patients with NAFLD.

Healing was successfully achieved with percutaneous cannulated compression screw fixation, albeit with prolonged healing as is typical for this condition.
A lack of osteoclastic remodeling predisposes patients with osteopetrosis to fractures, commonly in long bones. Increased risks of infection, anesthesia, and broken hardware along with limited ability to compress bone may discourage operative management. Internal fixation should still be considered in select cases to limit displacement while allowing early range of motion.

Clinical findings and imaging studies led to the diagnoses of femoroacetabular impingement and diffuse tenosynovial giant cell tumor (TGCT). Comprehensive arthroscopic management and biopsy revealed a diagnosis of osteosarcoma. The patient subsequently underwent chemotherapy, surgical resection, and reconstruction.
Osteosarcoma of the proximal femur may mimic TGCT on imaging studies because osteosarcoma may show changes suggestive of inflammation. We recommend heightened clinical awareness and a comprehensive differential workup in the management of presumed TGCT about the hip in the pediatric patient population.

Imaging demonstrated a cuboid fracture with inferomedial dislocation and associated nondisplaced midfoot fractures. Treatment consisted of closed reduction and percutaneous pinning (CRPP) using Kirschner wire fixation. His postoperative recovery was uneventful with full return to activities.
Cuboid fracture-dislocations are exceedingly rare, and subsequently, there is a paucity of treatment recommendations in the literature. To the best of our knowledge, this is the first reported successful closed reduction with percutaneous pinning for a cuboid fracture with associated dislocation. CRPP is a potential treatment option for this injury.

Mounting evidence, however, indicates that tissue-resident memory T cells (Trms) are superior at controlling many pathogens, including Mycobacterium tuberculosis (M. tuberculosis), and can be quite different from those in circulation. Using freshly resected lung tissue, from individuals with active or previous TB, we identified distinct CD4+ and CD8+ Trm-like clusters within TB-diseased lung tissue that were functional and enriched for IL-17-producing cells. M. tuberculosis-specific CD4+ T cells producing TNF-α, IL-2, and IL-17 were highly expanded in the lung compared with matched blood samples, in which IL-17+ cells were largely absent. Strikingly, the frequency of M. tuberculosis-specific lung T cells making IL-17, but not other cytokines, inversely correlated with the plasma IL-1β levels, suggesting a potential link with disease severity. Using a human granuloma model, we showed the addition of either exogenous IL-17 or IL-2 enhanced immune control of M. tuberculosis and was associated with increased NO production. Taken together, these data support an important role for M. tuberculosis-specific Trm-like, IL-17-producing cells in the immune control of M. tuberculosis in the human lung.Hypothalamic feeding circuits have been identified as having innate synaptic plasticity, mediating adaption to the changing metabolic milieu by controlling responses to feeding and obesity. However, less is known about the regulatory principles underlying the dynamic changes in agouti-related protein (AgRP) perikarya, a region crucial for gating of neural excitation and, hence, feeding. Here we show that AgRP neurons activated by food deprivation, ghrelin administration, or chemogenetics decreased their own inhibitory tone while triggering mitochondrial adaptations in neighboring astrocytes. We found that it was the inhibitory neurotransmitter GABA released by AgRP neurons that evoked this astrocytic response; this in turn resulted in increased glial ensheetment of AgRP perikarya by glial processes and increased excitability of AgRP neurons. We also identified astrocyte-derived prostaglandin E2, which directly activated - via EP2 receptors - AgRP neurons. Taken together, these observations unmasked a feed-forward, self-exciting loop in AgRP neuronal control mediated by astrocytes, a mechanism directly relevant for hunger, feeding, and overfeeding.
